About product

Q.PEAK DUO L-G8.2 is a powerful solar panel from Hanwha Q CELLS, the Korean-German manufacturer. It’s an ideal solution for rooftop arrays on commercial and industrial buildings and ground-mounted solar power plants. It performs well in all kinds of weather and shows great shading tolerance.

Features:

  • 420W power output
  • 19.6% efficiency or higher
  • 144 half-cut solar cells
  • Maximum system voltage: 1500 (IEC) /1500 (UL)
  • MC4-Evo2 connectors

Impressive output for large solar systems

Q.PEAK DUO L-G8.2 is best suited for systems of a larger scope rather than simple home installations. It provides solid 420 watts power output with 19.6% efficiency. The panel is relatively inexpensive so you can build large power systems with it.

Great for all kinds of weather

The innovative all-weather technology provides optimal yields, whatever the weather. It features excellent low-light and temperature behavior. At the same time the panel isn’t afraid of harsh weather conditions: solar cells are protected by a high-tech aluminum alloy frame, certified for high snow (5400Pa) and wind loads (2400Pa).

Half-cut cell design provides better shading tolerance

The panel from Q CELLS has 144 half-cut cells. Split cell design contributes to higher durability of a module, makes it less susceptible to micro cracks and hot spots development. Most importantly, it increases shading tolerance of a panel, as two halves of a module become completely independent from each other.


Solid warranty make Q CELLS panels a good investment

Q CELLS panels come with a 12-year product warranty and 25-year linear performance warranty. The module retains at least 98% of nominal power during the first year in operation. Thereafter the maximum degradation rate doesn’t exceed 0.54% per year. You can expect at least 93.1% of nominal power after 10 years and at least 85% after 25 years.

a very very good performance in clouds. I expected less to be honest, but this is a top-tier product.

We purchased a sizable amount of these panels half a year ago for our enterprise in California. The installation was finished just recently. So far the panels have allowed us to lower our energy expenses by 62% and we expect even more from them in the following months. Many thanks to A1 SolarStore staff who handled the order very professionally and helped a lot along the way.

the panels are engineered in Germany, but made in China.
how do they handle the winter

As long as they aren’t covered with snow, they do great on sunny days. Of course, the output is going to be 30-50% less just because there aren’t as many sun hours.

FAQ

How much is shipping and how long is delivery?
Our standard shipping charge is $250 for up to 11 panels and it is increased by $25 for every 4 additional panels. In the event, the product is only available on East or West coast custom quote will be sent to you before the order is processed. Normally, we are able to deliver solar panels within 7 business days.
What is the difference between low price panels and top price panels?
With top tier solar panels, you pay for the brand name, proprietary new technology, higher energy output, and better warranty support.
What are the dimensions of the panel?
Please refer to the product datasheet on the product page. We have a datasheet for every product we sell.
How long is the warranty on the panel?
In general, manufacturers provide a 25 year-long performance warranty and a 10 year-long equipment guarantee. Some manufacturers offer 12-15 years of warranty. More information is available in our warranty support section.
Which panels do you recommend for RV, marine?
We recommend Panasonic and Mission Solar panels for smaller systems as their high energy output and excellent craftsmanship guarantee years of service.
Can this panel be used with a 12v system?
Any of our panels can be used for a 12v system with a properly selected inverter and charge controller.
Can I pick up this panel from your fulfillment center to save on shipping?
Yes, we can set up a pick up at a local distributor. Please call to discuss options and stock availability.
How do I connect these panels?
To achieve the best system efficiency, panels should be connected in series to create higher voltage.
How many panels do I need?
This number is determined by your average energy needs. Depending on the type of panels and energy consumption, you might need anywhere from 12 to 45 solar panels. Remember, the more panels you install the more energy you will get.Please use our solar calculator to estimate your energy consumption and plan on building a solar system that will exceed your energy needs by 25%.
How do I build a solar system?
Please use our solar calculator to estimate what equipment you need. Choose your panels, microinverters, inverters, and solar batteries if necessary.Please note that we do not offer solar system design or installation.
How do solar panels compare?
Solar panels differ by power output, voltage, connection type, size, efficiency, and weight. Some solar panels might be sold together with microinverters as a set.
Can I build a solar system by myself as a Do It Yourself project?
Yes, it is possible if you understand what solar equipment you need and how to connect it together. However, please be mindful that handling your own electrical work without having proper experience might cause life-threatening injuries. Please contact a certified electrician if you do not possess appropriate electrical skills.
Can I connect and charge my solar panel battery directly with the solar panel?
We do not recommend using the solar panel without the charge controller. Using solar panels without the charge controller might damage the batteries.
Can I drill holes into the aluminum frame for mounting?
We do not recommend drilling any new holes to the aluminum frame of the panel as it could damage the internal circuit and solar cells. (Also, any modification to the panel will void the warranty). We recommend only using the pre-drilled holes for mounting.
Do solar panels require maintenance? Can I wash my solar panel?
Solar panels generally require very little maintenance. We recommend cleaning the solar panel with water, glass cleaner (Windex) and microfiber cloth.
Will my panel produce power in an overcast condition?
While solar panels require sunlight to generate solar energy, they will still work in cloudy weather. Even on a cloudy day, solar panels will produce energy just not as much.
Will my panels produce power if covered with snow?
Solar panels cannot produce electricity if covered with snow.
What is the best direction for a solar panel to face?
The best direction for a solar panel to face is the South
